Much needed rain & big temperature drop ahead for the St. Louis region

News

ST. LOUIS – A strong cold front will bring big changes over the next 24 hours. After nearly 3 weeks of dry weather, rain will move in this evening.

Sunday will once again be warm with highs climbing into the low 80s ahead of the approaching cold front. Clouds will increase and thicken from the northwest to the southeast through the afternoon.

Rain chances increase Sunday afternoon from the northwest to the southeast. Showers and a few storms will develop along the front. Rain and some thunder will then continue into the overnight hours, potentially lingering into Monday morning.

Rainfall amounts look to be in the 1/2 ” to 1″ range.

Temperatures will fall to the upper 40s and low 50s overnight, so Monday morning will be chilly and damp with cloudy skies. Some clearing is possible at times on Monday and highs will only climb to the mid to upper 60s. A few spot showers may develop again in the afternoon and evening.

The autumn-like feel will stick around the entire week. Wednesday will be a bit warmer, with highs rebounding into the low 70s, but another cold front will come through and bring another shot of chilly air to the region for the end of the work week.
